Rigid Duct Insulation Alternative

After some hunting today I found a local HVAC company that had R8 flex in stock. Yes, extra cost and a bit of a waste removing the plastic inner air duct but using just the outer insulation sleeve is going to make my project so much easier.

Leave the liner in it to start Earnie. Pulling just the insulation over a pipes sharp edge without the plastic "guts" is a pain in the behind. Goes much faster if you put the guts over the pipe end then pull from there.
